Neooccultibambusa jonesii, a novel taxon within Occultibambusaceae

A new species of Neooccultibambusa, N. jonesii, is introduced from Ammophila arenaria collected in Italy. The novel taxon is characterized by immersed to semi-immersed ascomata in fissures of bark, a two-layered peridium, hyaline to brown ascospores and in producing chlamydospores in culture; these characters are typical of Neooccultibambusa. Multigene phylogenies based on analysis of 28S, 18S and RPB2 sequence data, indicate that N. jonesii belongs in the family Occultibambusaceae and is closely related to N. chiangraiensis, but is phylogenetically distinct. Neooccultibambusa jonesii can be differentiated from N. chiangraiensis based on the number of septa, the larger and mature dark brown ascospores and in lacking a mucilaginous sheath. We provide a description and photoplates of the new species and compare it with related species, together with phylogenetic inferences based on combined sequence data.
